Type.

PERU. Ferreyra 3120 (lectotype, designated by Garay (1978: 200): AMES!, isolectotype: USM; UGDA-DLSz!-drawing).

Diagnosis.

Plants up to 29-37 cm tall. Leaf 1, basal, petiolate; petiole 10.5-14 cm long; blade 8-10 cm long, ca. 5.0 cm wide, oblong-elliptical to ovate, oblique, acute or shortly acuminate, cuneate to subcordate at base. Scape glabrous below, finely pubescent or ciliate above, with 3-5, non-foliaceous sheaths. Inflorescence 5-7 cm long, conical, subdensely many-flowered. Flowers greenish or greenish-white. Floral bracts 4.3 mm long, lanceolate, glabrous. Pedicellate ovary 6.2 mm long, glandular. Dorsal sepal 4.1-5.0 mm long, 1.2-2.1 mm wide, ovate-lanceolate to narrowly elliptical, subacute, concave, 3-veined. Petals 3.3-4.0 mm long, 0.3-0.7 mm wide, obliquely linear-lanceolate, subobtuse, more or less oblique or curved, 1-veined, glabrous. Lateral sepals 4.2 mm long, 1.6-2 mm wide, obliquely elliptical, subacute to obtuse, 2-3-veined, margin very sparsely ciliate. Lip 3.2-3.6 mm long, 1.8-3.0 mm wide, deeply concave, basally gibbose, shortly unguiculate, obovate to suborbicular, apex rounded with a minute apiculus; disc with three transversely anastomosing veins. Gynostemium 1.8-2.0 mm long. Fig. 11 .

Habitat and ecology.

Terrestrial in Yungas montane humid, and cloud forest, also in montane Tucumano-Boliviano forest, at altitudes between 2380-3000 m. Flowers in March.

Representative specimens.

Bolivia. Santa Cruz: J.M. Caballero, Comunidad Siberia, ca. 1-2 km arriba del pueblo de Siberia, sobre un camino vecinal, entrando hacia el Parque Nacional Amboro. 17°49.36'S, 64°45.14'W, 3001 m. 26 March 2004. M. Mendoza & S. Acebo 912 (LPB!), Vallegrande. Tucumano-Bolivano. 18°34 ’28” S 64°02 ’33” W, 2387 m. Parada et al. 4208 (LPB!). Fig. 2 .

Notes.

The lip of the specimen collected by Parada et al. 4208 (LPB) differs somewhat in shape from the typical form of that of C. longipetiolata , which is obovate rather than suborbicular in outline.
